High-Purity Diesel Exhaust Fluid (AUS32) for SCR Systems – 10kg

The National VI Vehicle Urea Solution, also known as Diesel Exhaust Fluid (DEF) or AUS32, is a premium-grade consumable designed specifically for modern diesel engines equipped with Selective Catalytic Reduction (SCR) systems. Formulated to meet the stringent China National VI emission standards (equivalent to Euro VI), this solution acts as a critical reducing agent. When injected into the hot exhaust stream, it undergoes a chemical reaction that converts harmful Nitrogen Oxides (NOx) into harmless nitrogen and water vapor. This product is essential for ensuring your heavy-duty trucks and diesel vehicles remain compliant with environmental regulations while maintaining peak engine efficiency. It is non-toxic, non-flammable, and safe to handle, making it the standard choice for fleet operators and individual vehicle owners alike.

Application Scenarios

• Heavy-Duty Transportation: Ideal for long-haul trucks, logistics fleets, and commercial vehicles operating under National IV, V, and VI emission standards.
• Construction & Industrial Machinery: Suitable for non-road mobile machinery and construction equipment equipped with SCR after-treatment systems.
• Routine Refilling: Designed for regular top-ups during vehicle maintenance or at service stations to prevent SCR system warnings and engine derating.
• Fleet Management: A bulk-ready solution (10kg pack) perfect for maintenance depots managing multiple diesel vehicles.

Product Functions & Benefits

• NOx Reduction: Effectively reduces Nitrogen Oxide emissions by up to 90% through selective catalytic reduction, significantly lowering the vehicle’s environmental footprint.
• Emission Compliance: Ensures vehicles meet strict National VI (China 6) and international emission regulations, avoiding fines and inspection failures.
• Engine Protection: By facilitating efficient SCR operation, it helps prevent catalyst clogging and extends the lifespan of the exhaust after-treatment system.
• Fuel Efficiency Optimization: Allows the engine control unit (ECU) to optimize combustion timing for better fuel economy, as it relies on the SCR system rather than EGR (Exhaust Gas Recirculation) alone for emission control.

Product Features

• High Purity Formula: Manufactured with ultra-pure urea and deionized water (32.5% concentration) to prevent injector clogging and crystallization.
• Safe & Stable: Non-toxic, non-irritating, and non-flammable liquid, ensuring safe storage and handling for drivers and mechanics.
• Broad Compatibility: Fully compatible with all major SCR systems requiring AUS32/DEF, covering National IV, V, and VI engines.
• Convenient Packaging: The 10kg durable plastic container is designed for easy pouring and secure transport, minimizing spillage risks.
